Continuity mistake: When Pinhead is just about to start killing everyone in The Boiler Room night club, a man catches the first hooked chain that Pinhead unleashes. Yet when you look closely as you see the man holding the chain there is no hook, but a piece of wire.

Continuity mistake: In the scene where Pinhead is in the church, he stands behind the table, and the candle to the right of him is straight. He then pushes the cross off the front, look at the candle, it is now on a slant then in a split second the candle is straight again as if it had never been touched.
